# Plancks constant?

I was wondering what exactly Plancks constant describes. Do all photons have the energy h and the measure of the energy in an electromagnetic wave is just related the the frequency which photons make contact with some particle, keeping in mind that they all still have the same exact energy? Or do photons exist in a variety of energies?

I also want to ask if photons have measurable properties such as wavelength or some relative mass?

Photons have varying energies according to the formula $$e=h\nu$$ where h is Planck's constant and $$\nu$$ is the frequency. Wavelength is the inverse of frequency. Higher frequency means higher energy.

PHOTON and PHYSICS OF FTL-PARTICLE IGNORONS
The old concept of a photon with wave-particle duality characters has been changed.Now the photon is not considered as a single particle but an entangled quantum state of two particle assembly.This is based on the reality that challenged Einstein's concept that nothing can go faster than "c".The ignorons physics brings the FTL-particles or entities,which when encounters a freed liberated charge,like an electron or proton or neutron,or positron,instantaneously unite to give birth to Electromagnetic radiation as a two body system of entangled quantum state with spin one and levitation induced masslessnes due to compatiable magnetic fields of this new quantum state.

This material belongs strictly in Theory Development. The links are to material written by Syed, and do not represent mainstream scientific opinion. It smacks of self-promotion. Syed also has written on his theory of anti-gravity too.

It is not fair to have a legitimate thread hijacked for an individual's own agenda - i.e. pushing a "crackpot" viewpoint. The OP asked a reasonable question, and deserves a reasonable answer.
